What is the number one rule of statistics?

Can you tell me, what is considered to be the most fundamental principle in the realm of statistics? It seems to be a cornerstone that guides researchers and analysts alike in their endeavors to draw meaningful conclusions from data. Is it perhaps the importance of maintaining a rigorous level of accuracy and precision, ensuring that every detail is accounted for and that biases are minimized? Or is it something more conceptual, like the need to always consider the underlying assumptions and limitations of any statistical model? I'm curious to know your thoughts on this fundamental question.
